- Table 1: Comparative pharmacokinetic characteristics of GH-related research peptides in preclinical models. Values are approximate and vary by model and study design.
- This comparison illustrates how pharmacokinetic differences among GH secretagogues influence experimental design. Researchers looking to study the effect of acute GH pulses use short-acting compounds like Ipamorelin. Those studying effects of sustained GH elevation use longer-acting compounds like CJC-1295 with DAC.
